Biblatex 出版物（年份）以粗体显示

Question

我试图以粗体显示年份和括号

作者（年）：

这是 MWE

\documentclass[12pt, bibliography=totocnumbered, listof=totoc]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[ngerman]{babel}
\usepackage{csquotes}

\usepackage{filecontents}

%Bibliotheken
\usepackage

doi=false,isbn=false,url=false,
uniquename=false,bibencoding=utf8, date=year, giveninits=true, terseinits=false, dashed=false]
{biblatex}


%Colon after year
\renewcommand{\labelnamepunct}{\mkbibbold{\addcolon}\space}

%Year and parantheses in bold
\DeclareFieldFormat{date}{\mkbibbold{#1}}
\DeclareFieldFormat{parens}{\mkbibbold{\mkbibparens{#1}}}


\begin{filecontents}{\jobname2.bib}
@Article{Hansen2011,
  author  = {Hansen, Peter R. and Lunde, Asger and Nason, James M.},
  title   = {The Model Confidence Set},
  journal = {Econometrica},

我尝试过以某种方式使用 \mkbibbold，但效果不佳。如果能给出简短的解释就更好了。

Answer 1

biblatex-ext定义字段的附加格式，并在其中biblabeldate控制“参考书目中标签日期的格式authoryear”，因此这就是您必须用于您的目的的格式：

\DeclareFieldFormat{biblabeldate}{\mkbibbold{\mkbibparens{#1}}}

除此之外，尽管从技术上来说，你可以nametitledelim用重新定义\renewcommand，因为它nametitledelim是上下文敏感的分隔符，但在使用时，\renewcommand你会失去这种上下文敏感度。因此，你最好使用适当的专用\DeclareDelimFormat：

\DeclareDelimFormat[bib,biblist]{nametitledelim}{\addcolon\space}

（为此需要以粗体字体显示冒号，如biblabeldate选项的格式指令中所设置的那样）。punctfont=true

在全：
